How IVF Works: A Step-by-Step Guide to the Process

How to Do IVF: The Core Steps

In vitro fertilization is a multi-step fertility treatment where eggs are retrieved, fertilized with sperm in a lab, and the resulting embryo is placed into the uterus. The process typically takes four to six weeks from start to pregnancy test.

1. Ovarian Stimulation

You self-administer hormone injections for 8 to 14 days to stimulate your ovaries to produce multiple eggs rather than the single egg released in a natural cycle. Progress is monitored with blood tests and ultrasounds.

2. Egg Retrieval

When follicles are mature, a thin needle is guided through the vaginal wall under ultrasound to collect the eggs. The procedure takes about 20 minutes and is done under sedation.

3. Fertilization and Embryo Culture

Eggs are combined with sperm in the lab, or a single sperm is injected directly into each egg. Embryologists monitor cell division for 3 to 5 days before selecting the strongest embryo.

4. Embryo Transfer

A catheter passes the embryo through the cervix into the uterus. This is a quick, painless procedure, followed by a two-week wait before a pregnancy test.

Who Should Consider IVF

IVF is used for blocked fallopian tubes, male factor infertility, endometriosis, unexplained infertility, and when other treatments like ovulation induction or IUI have failed. Age and ovarian reserve heavily influence success rates.

What to Expect During a Cycle

• Daily injections with mild discomfort at the injection site
• Regular clinic visits for monitoring
• Mild cramping or bloating during stimulation
• Short recovery after retrieval
• Emotional ups and downs during the two-week wait

Key Factors That Affect Success

Risks and Costs

IVF costs vary widely by country and clinic. Common risks include ovarian hyperstimulation syndrome, multiple pregnancy, and emotional stress. Discuss a clear financial and medical plan with your reproductive endocrinologist before starting.
